Human factors: HSE issues major accident warning to offshore firms

Britain’s offshore oil and gas installations are held to high regulatory standards, but human error can still lead to a major incident.

That’s the message from the Health and Safety Executive (HSE), who are urging offshore companies to take a closer look at what’s widely known in the sector as human factors.

HSE inspects human factors on offshore installations, with a particular focus on safety critical tasks.

Safety critical tasks have the potential to initiate or escalate a major accident on an installation.

Mary Marshall, a principal specialist inspector at HSE, says it is necessary offshore firms like Apache identify safety critical tasks carried out on their offshore installations.

Mary said: “Offshore companies need to understand and evaluate where and how these safety critical tasks might be vulnerable to human error. Safety Critical Task Analysis (SCTA) is an established, structured process that will help companies demonstrate that these tasks can be carried out safely, reliably and that the risks are managed to as low as reasonably practicable. This will include consideration of the design of the equipment, details of the tasks and the factors which support task performance.”

HSE has noted a number of offshore firms have launched SCTA programmes with varying degrees of success.

Common failings that HSE has identified with these SCTA programmes include a lack of sustained commitment and progress with the work, and inconsistencies in the quality of assessments.
